Is there anyway to build your own Wi-Fi 7 access point?

[Snowleopard]

I was wondering if there is any motherboard where I can have 1 m.2 slot for the nvme and boot linux and then an additional 4 or 8 m.2 slots for separate laptop BE200 network interface cards to drive 8 or 16 antennas as a high capacity access point? and open source software like pfsense to manage it?

If there is, it would be more cost effective than the insane prices manufacturers want for wi-fi 7 routers or access points right now.
